CDM-A100 Series
1. Introduction
The CDM-A108 and CDM-A116 are 24-bit analog input modules that
significantly increase the number of analog channels in a datalogger system.
The CDM-A108 has eight differential channels and the CDM-A116 has 16
differential channels.
The CDM-A108 and CDM-A116 feature a 24-bit analog-to-digital converter
and a low-noise, analog front-end to provide superior analog measurements.
They also support period average measurements and include both current and
voltage excitation channels.
Connect up to 50 CDMs to a single datalogger.
Throughout this manual, any reference to the CDM-A100 applies to both the
CDM-A108 and CDM-A116, unless specifically noted.
